Setting them up and knocking them down.
JEGS guys were fantastic. Here's the recommendation (their smallest diameter booster):
Booster: https://www.jegs.com/i/JEGS/555/631700/10002/-1
Master Cylinder: https://www.jegs.com/i/JEGS/555/631390/10002/-1
I also needed to get an extension rod for the brake booster. The welded up do-dad that was on the booster will not be reused....
Jegs had a kit, but I decided to go to McMaster and get some high strength steed rod and a better clevis. We'll see how it all turns out. While at JEGS, I also got some new ball fittings so that a proper throttle /carburator connection can be made.
I'm an accountant by trade, so all of this mechanical stuff is new to me. I really appreciate all of the help from the Forum on this project. It's all coming together.... (I hope).
